Question Help The principle of redundancy is used when system reliability is improved through redundant or backup components. Assume that a student's alarm clock has a 6.7% daily failure rate. Complete parts (a) through (d) below. a. What is the probability that the student's alarm clock will not work on the morning of an important final exam? (Round to three decimal places as needed) b. If the student has two such alarm clocks, what is the probability that they both...

9. The principle of redundancy is used when system reliability is improved through redundant or backup components. Assume that a student's alarm clock has a 10.1% daily failure rate. Complete parts (a) through (d) below. c. What is the probability of not being awakened if the student uses three independent alarm clocks? (Round to five decimal places as needed.) 14.In a market research survey of 2006 motorists, 281 said that they made an obscene gesture in the previous month. Complete...
10. The principle of redundancy is used when system reliability is improved through redundant or backup components. A region's government requires that commercial aircraft used for flying in hazardous conditions must have two independent radios instead of one. Assume that for a typical flight, the probability of a radio failure is 0.0028. What is the probability that a particular flight will be threatened with the failure of both radios? Describe how the second independent radio increases safety in this case....

8.With one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the entire batch is accepted if every item in the sample is okay. A company has just manufactured 1591 CDs, and 196 are defective. If 3 of these CDs are randomly selected fortesting, what is the probability that the entire batch will be accepted? Does this outcome suggest that the entire batch consists of good CDs? Why or why not? If...

Bob sets two alarm clocks (battery-powered) to be sure he arises for his Monday 8:00 a.m. accounting exam. There is a 90 percent chance that either clock will wake Bob. (a) What is the probability that Bob will oversleep? (Round your answer to 4 decimal places.) Probability (b) If Bob had three clocks, would he have at least a 85 percent chance of waking up? Yes No
Hospitals typically require backup generators to provide electricity in the event of a power outage. Assume that emergency backup generators fail 39% of the times when they are needed. A hospital has two backup generators so that power is available if one of them fails during a power outage. Complete parts (a) and (b) below. a. Find the probability that both generators fail during a power outage. (Round to four decimal places as needed.) b. Find the probability of having...
